QuickBasic
Microsoft QuickBASIC (also QB) is an Integrated Development Environment (or IDE) and compiler for the BASIC programming language that was developed by Microsoft. QuickBASIC runs mainly on DOS, though there was also a short-lived version for the classic Mac OS. It is loosely based on GW-BASIC but adds user-defined types, improved programming structures, better graphics and disk support and a compiler in addition to the BASIC interpreter, interpreter. Microsoft marketed QuickBASIC as the introductory level for their BASIC Professional Development System. Microsoft marketed two other similar IDEs for C and Pascal, viz QuickC and QuickPascal. History Microsoft released the first version of QuickBASIC on August 18, 1985 on a single 5.25-inch 360 KB floppy disk. QuickBASIC version 2.0 and later contained an Integrated Development Environment (IDE), allowing users to edit directly in its on-screen text editor. Although still supported in QuickBASIC, line numbers became optional. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Learn BASIC Now
''Learn BASIC Now'' is a book series written by Michael Halvorson and David Rygmyr, published by Microsoft Press. The primers introduced computer programming concepts to students and self-taught learners who were interested in creating games and application programs for early personal computers, including IBM-PC compatible systems and the Apple Macintosh. ''Learn BASIC Now'' included software disks containing the QuickBASIC, Microsoft QuickBASIC Interpreter and the book’s sample programs. The books were influential in the popularization of the BASIC language and released during a significant growth phase of the personal computer industry when the installed base of BASIC programmers hit four million active users. Since the books were distributed by Microsoft and featured a robust, menu-driven programming environment, ''Learn BASIC Now'' became an important catalyst for the learn-to-program movement, a broad-based computer literacy initiative in the 1980s and 1990s that encouraged ...

QBasic
QBasic is an integrated development environment (IDE) and BASIC interpreter, interpreter for a variety of dialects of BASIC which are based on QuickBASIC. Code entered into the IDE is compiled into an intermediate representation (IR), and this IR is immediately executed on demand within the IDE. Like QuickBASIC, but unlike earlier versions of Microsoft BASIC, QBasic is a structured programming language, supporting constructs such as subroutines. Line numbers, a concept often associated with BASIC, are supported for compatibility but are not considered good form, having been replaced by descriptive line labels. QBasic has limited support for user-defined data types (record (computer science), structures), and several primitive types used to contain strings of text or numeric data. It supports various inbuilt functions. For its time, QBasic provided a state-of-the-art IDE, including a debugger with features such as on-the-fly expression evaluation and code modification.

Microsoft BASIC
Microsoft BASIC is the foundation software product of the Microsoft company and evolved into a line of BASIC interpreters and compiler(s) adapted for many different microcomputers. It first appeared in 1975 as Altair BASIC, which was the first version of BASIC published by Microsoft as well as the first high-level programming language available for the Altair 8800 microcomputer. During the home computer craze of the late-1970s and early-1980s, Microsoft BASIC was ported to and supplied with many home computer designs. Slight variations to add support for machine-specific functions, especially graphics, led to a profusion of related designs like Commodore BASIC and Atari Microsoft BASIC. As the early home computers gave way to newer designs like the IBM Personal Computer and Macintosh, BASIC was no longer as widely used, although it retained a strong following. The release of Visual Basic rebooted its popularity and it remains in wide use on Microsoft Windows platforms in its m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conditional (programming)
In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a ''condition''. Conditionals are typically implemented by selectively executing instructions. Although dynamic dispatch is not usually classified as a conditional construct, it is another way to select between alternatives at runtime. Terminology Conditional statements are imperative constructs executed for side-effect, while conditional expressions return values. Many programming languages (such as C) have distinct conditional statements and conditional expressions. Although in pure functional programming, conditional expressions do not have side-effects, many languages with conditional expressions (such as Lisp) support conditional side-effects. If–then(–else) The if–then or if ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

QuickPascal
Microsoft Pascal is a discontinued implementation of the Pascal programming language developed by the Microsoft Corporation for compiling programs for running on its MS-DOS and Xenix operating systems and, in later versions, on OS/2 (like many other Microsoft programming tools, albeit they are only capable of generating 16-bit programs for the latter). Overview Microsoft Pascal version 1.0 was released in 1980. The last version of Microsoft Pascal to be released was version 4.0 in 1988, when Microsoft Pascal was superseded by Microsoft QuickPascal, a cheaper development tool that Microsoft produced in order to compete with Borland's Turbo Pascal. Microsoft Pascal was priced at , whereas QuickPascal was priced between , and the differences between the two were similar to those between Microsoft BASIC Professional Development System and Microsoft QuickBASIC Microsoft QuickBASIC (also QB) is an Integrated Development Environment (or IDE) and compiler for the BASIC programm ...

QuickC
Microsoft QuickC is a discontinued commercial integrated development environment (IDE) product engineered by Microsoft for the C programming language, superseded by Visual C++ Standard Edition. Its main competitor was Borland Turbo C. QuickC is one of three Microsoft programming languages with IDEs of this type marketed in the same period, the other two being QuickBasic and QuickPascal.QuickPascal Programmers' Toolbox pp 3-6 QuickBasic later gave rise to Visual Basic as well as being included without a linker as QBasic in later versions of MS-DOS, replacing GW-BASIC. QuickC is a lineal ancestor of Visual C++. The three Quick language implementations were designed for power users (as opposed to professional developers, whom Microsoft supplied with programming languages in the form of expensive and more comprehensive implementations for the three languages in question as well as C++, Fortran, and Cobol) and educational use; in all three cases their major competitor was Borland ...

BASIC Interpreter
A BASIC interpreter is an Interpreter (computing), interpreter that enables users to enter and run programs in the BASIC programming language, language and was, for the first part of the microcomputer era, the default Application software, application that computers would launch. Users were expected to use the BASIC interpreter to type-in programs, type in programs or to load programs from storage (initially cassette tapes then floppy disks). BASIC interpreters are of historical importance. Microsoft's first product for sale was a BASIC interpreter (Altair BASIC), which paved the way for the company's success. Before Altair BASIC, microcomputers were sold as kits that needed to be programmed in machine code (for instance, the Apple I). During the Altair period, BASIC interpreters were sold separately, becoming the first software sold to individuals rather than to organizations; Apple BASIC was Apple's first software product. After the Altair 8800, MITS Altair 8800, microcomputers w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GW-BASIC
GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from IBM BASICA. Functionally identical to BASICA, its BASIC interpreter is a fully self-contained executable and does not need the Cassette BASIC ROM found in the original. It was bundled with MS-DOS operating systems on IBM PC–compatibles by Microsoft. The language is suitable for simple games, business programs and the like. Since it was included with most versions of MS-DOS, it was also a low-cost way for many aspiring programmers to learn the fundamentals of computer programming. Microsoft also sold a BASIC compiler, BASCOM, compatible with GW-BASIC, for programs needing more speed. According to Mark Jones Lorenzo, given the scope of the language, "GW-BASIC is arguably the ''List_of_Latin_phrases_(N)#ne_plus_ultra, ne plus ultra'' of Microsoft's family of line-numbered BASICs stretching back to Altair BASIC — and perhaps even of line-numbered BASIC in general." With the release of M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Visual Basic (classic)
Visual Basic (VB), sometimes referred to as Classic Visual Basic, is a third-generation programming language, third-generation programming language based on BASIC, as well as an associated integrated development environment (IDE). Visual Basic was developed by Microsoft for Windows, and is known for supporting rapid application development (RAD) of graphical user interface (GUI) applications, event-driven programming, and both consumption and development of Component-based software engineering, components via the Component Object Model (COM) technology. VB was first released in 1991. The final release was version 6 (VB6) in 1998. On April 8, 2008, Microsoft stopped supporting the VB6 IDE, relegating it to legacy system, legacy status. The Microsoft VB team still maintains compatibility for VB6 applications through its "It Just Works" program on supported Windows operating systems. Visual Basic .NET (VB.NET) is based on Classic Visual Basic. Because VB.NET was later rebranded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Video Game
A video game or computer game is an electronic game that involves interaction with a user interface or input device (such as a joystick, game controller, controller, computer keyboard, keyboard, or motion sensing device) to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset. Most modern video games are audiovisual, with Sound, audio complement delivered through loudspeaker, speakers or headphones, and sometimes also with other types of sensory feedback (e.g., haptic technology that provides Touch, tactile sensations). Some video games also allow microphone and webcam inputs for voice chat in online gaming, in-game chatting and video game livestreaming, livestreaming. Video games are typically categorized according to their hardware platform, which traditionally includes arcade video games, console games, and PC game, comp ...

99 Bottles Of Beer
"99 Bottles of Beer" or "100 Bottles of Pop on the Wall" is a traditional reverse counting song from the United States and Canada. It is popular to sing on road trips, as it has a very repetitive format which is easy to memorize and can take a long time when sung in full. In particular, the song is often sung by children on long school bus trips, such as class field trips, family road trips, or on Scout or Girl Guide outings. In computer science, printing the lyrics of 99 Bottles of Beer is a commonly used task to demonstrate esoteric programming languages. History Lyrics The song's lyrics are as follows, beginning with n=99: (n) bottles of beer on the wall. (n) bottles of beer. If one of the bottles just happen to fall, (n−1) bottles of beer on the wall. \layout The same verse is repeated, each time with one bottle fewer, until there is none left. Variations on the last verse following the last bottle going down include lines such as: No more bottles of beer o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Utility Software
Utility software is a program specifically designed to help manage and tune system or application software. It is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users. However, utilities often form part of the application . For example, a batch job may run user-written code to update a database and may then include a step that runs a utility to back up the database, or a job may run a utility to compress a disk before copying files. Although a basic set of utility programs is usually distributed with an operating system (OS), and this first party utility software is often considered part of the operating system, users often install replacements or additional utilities. Those utilities may provide additional facilities to carry out tasks that are beyond the capabilities of the operating system. Many utilities that might affect the entire computer system require the user to have el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
